To all whom t may conce/m:

Be it known that we, CLARENCE H. How- Ann and Hanny M. PrLAGnn, citizens of the United States, residing 4at the city of St. Louis, `State of Missouri, have inventeda certain new and useful Improvement 1n Truck Construction, of which the following is a full, clear, rand exact descriptlon, such as will enable -othersskilled in ythe art to which it -appertains to make and use the same, reference being had to the -acconipanying'drawings, forming .part of this specificatlon, in which- Figure 1 is a top plan view ofthe side portionof a truck of our improved construction. Fig. 2 is'a side elevational view of the truck with parts thereof in vertical seotion.- Fig. 3 is an enlarged detail section taken 4approximately on the -line 3-3 of Fig. 2. Fig. 4 an 'enlarged detail section taken approximately on the line 4 4 of Fig. 2. s

Our invention relates ,generally to truck construction and more specifically to -a new and improved construction and arrangement of the truck frame side -rails or wheel pieces and the truck squali-zing members and this application should be read in -connection with an application on truck construction filed by `us November 18th, 1912, Serial Nunn ber 73e,o99. j

The principal object of our invention is to produce a truck wherein the equalizing fmeinbe-rs are disposed and combined with parts of the truck frame so that they will in no wise interfere with the free inspection' and repair of the brakes, brake heads, 'and other parts 'of the truck equipment within the .truck frame.

Further objects of 4our invention are -to construct a truck frame having 'wheel .pieces which are substantially box shape .throughout their entire length thereby providing an exceptionally strong and rigid construction, to arrange the rigid and flexible e ualizing members within the .hollow whee pieces whereby they ai protected from injury and providing a very 'compa-ct structure to materially increase thestrength of the truck and decrease the weight thereof'. and to provide a construction wherein-the weight of the frame, and parts carried thereby, is evenly distributed upon the various journal boxes. n

To the above purposes our invention consists in certain novel features of construction and arrangement of parts hereinafter more fully described and e aimed.

As illustrated 4in the accompanying drawings our invention. is shown as applied to a six-wheel truck, but it will be readily understood 4that our invention is not limited to use on six-wheel trucks, bu't may be employed on trucks having other Wheel arrangements.

Referring -bv numerals to the accompanying drawings, 1 designates the `wheels mounted upon the usual axles 2z the ends -of which latter are jou'rnaled in suitable Ebones l3.

n lOur improved truck frame, as shown, is flor-mcd Vin a single piece, preferably by rcasting, and comprises hollow wheel pieces 4, flanged end rai-ls 5, flanged cross transoms G, and flanged wheel gua-rds 7, which latter j may be dispensed with if desired. The hollow Wheel .piece which is lsubstantially 'box shape throughout its entire length comprises a top plate or wall 8, vertically disposed parallel side Walls 9, and a bottom wall or plate 10. y The portions of the side walls 9 directly above thejour-nal boxes 3 are extendeddownward a short distance, thereby slightly increasing the depth of the wheel piece adjacent to th'e journal'boxes and at the points Where 4the pcdestals 11 `are fixed. The jaws of the pedestals extend below the 'wheel pieces and embrace the .jou'rnal boxes 3 and the lower ends of the jaws of the `pedeslals are 4u-n-ited by-tie straps 12. The bottom wall 10 of the wheel piece is notched or cut away, as designa-ted by 13, immediately above each journal box thereby permitting the wheel .piece to move downward with respect to the journal boxes. Formed in the hollow wheel pieces and preferably in the under side thereof at pointsnear the ends are openings 14 which readily permit the insertion or removaly of the equalizing members. Arranged within the hollow wheel piece fand rest/ing upon each journal box is a rigid equalizingmember 15 and bearn on the ends of each adjacent pair 'of rlgid equalizing members are tlexible equalizm'g members 16, preferably in the form of halfellipt-ic springs, the same bearing against the top wall or plate of the wheel piece. The ends of the rigid equali-zing bars 15 at the extremities of the wheel piece lare preferably 'engaged by links 1f?, the same being 4 i scribed, the truck frame is yieldingly sup,-

ported upon the journal boxes and the equal -izing members are located wholly within the hollow wheel pieces where they are'protect ed from injury, prevented from dropping on to the track in case they become broken and said-parts are disposed so that the brake heads, shown in dotted lines in Fig. 2, and other'parts within the truck are in plain sight where they may be readilyinspected or repaired. j

Our improved arrangement secures a flexible and universal equalization of' the weight of the truck .frame and parts carried thereby upon the journal 'boxes and by uti lizing half elliptic springs a high degree oy flexibility is obtained, thereby making the riding movement of the car more easy and gentle. l

We lhave shown and described a truck frame including its wheel pieces as being cast in a single piece, but it will be readily understood that a built-up structure having hollow wheel pieces may be provided and in either event the rigid and flexible equalizing members are arrangedl lwithin the hollow or box-like wheel pieces, thus in no wise intertering with the free inspection and repairs oil-the brakes and other parts within the truck frame and at the same time without materially increasing the height of the top of the truck frame Irom the tops of the truck rails.

It will be readily understood that minor changes in the size, or'm and construct-ion of the variousparts of our improved truck frame may be made and substituted for those herein shown'and described without departing from the spirit of our invention, the scope of which is set forth in the appended claims'.

v We claim: i

1. In a` truc-k construction, a truck frame having a wheel piece vwhich is hollow throughout its entire length and adapted to contain truck equalizing members, the bottom wall of which wheel piece is cut away at certain poin-ts to accommodate the journal boxes of the truck and to permit the insertion and removal of said equalizing members.

2. In truck construction, a truck frame having a wheel piece which is substantially box shape in cross section throughout its enhaving a wheel piece which issubs'tantially box shape in cross section throughout its entire lengthkin order to receive equalizing members of the truck, vand Vthe bottom walls ings to permit the insertion and 'removalof ksaid equalizing members.
